No power required for balancers

I find using balancers can be quite useless at times, because for example say I want to use one on the output of my generators to enforce even input and output, if there is ever a situation where low steam occurs and we run out of steam and thus power, the balancer will be 'offline' meaning it ends up just getting destroyed so it can be fixed...
Balancers would be more useful if they didn't consume power.

this is why you need a P15 backup power
